There are several types of plenoptic devices having their proprietary file format. At present there is no standard supporting the acquisition and transmission of multi-dimensional information for an exhaustive over-view of the different parameters upon which a light-field depends. As such acquired light-field data for different cameras have a diversity of formats. The notion of pixel beam, which represents a volume occupied by a set of rays of light in an object space of an optical system of a camera is thus introduced. The method according to the invention enables to provide data representative of a collection of pixel beams describing a first optical system that is agnostic since these data are obtained by imaging the collection of pixel beams through a second optical system. Such data representative of a collection of pixel beams enable the generation of parameterized output images from which post-processing.
A computer implemented method for generating data representative of at least one volume in an object space of a first optical system occupied by a set of rays of light passing through a pupil of said first optical system and an image conjugate, in said object space of the first optical system, of at least one pixel of a sensor associated to said first optical system, said volume occupied by said set of rays of light being called a pixel beam, comprising:
